Two amplifiers are connected one after the other in series (cascaded). The first amplifier has a voltage gain of 10 and the second has a voltage gain of 20. If the input signal is 0.01 Volt, calculate the output AC signal.
Show Hint
- 0 V
- 1 V
- 2 V
- 3 V
The Correct Option is C
Solution and Explanation
The total voltage gain of the cascaded amplifiers is the product of their individual gains: \[ {Total Gain} = 10 \times 20 = 200 \] Now, multiply the input signal by the total gain: \[ {Output signal} = 0.01 \times 200 = 2 \, {V} \] Thus, the output AC signal is 2 V.
Final Answer: 2 V.

Einstein's Explanation of the Photoelectric Effect:
Einstein explained the photoelectric effect on the basis of Planck’s quantum theory, where light travels in the form of small bundles of energy called photons.
The energy of each photon is hν, where:- ν is the frequency of the incident light
- h is Planck’s constant
The number of photons in a beam of light determines the intensity of the incident light.When a photon strikes a metal surface, it transfers its total energy hν to a free electron in the metal.A part of this energy is used to eject the electron from the metal, and this required energy is called the work function.The remaining energy is carried by the ejected electron as its kinetic energy.
